##
## Benford object:
##
## Data: airbnb_se_m$price
## Number of observations used = 8610
## Number of obs. for second order = 364
## First digits analysed = 2
##
## Mantissa:
##
## Statistic Value
## Mean 0.48
## Var 0.11
## Ex.Kurtosis -1.43
## Skewness 0.15

## The 5 largest deviations:

## digits absolute.diff
## 1 15 239.67
## 2 99 237.42
## 3 10 230.61
## 4 12 227.70
## 5 75 195.47
##
## Stats:
##
## Pearson's Chi-squared test
##
## data: airbnb_se_m$price
## X-squared = 7826.1, df = 89, p-value < 2.2e-16
##
##
## Mantissa Arc Test
##
## data: airbnb_se_m$price
## L2 = 0.057452, df = 2, p-value < 2.2e-16
##
## Mean Absolute Deviation: 0.007389969
## Distortion Factor: 2.066781
##
## Remember: Real data will never conform perfectly to Benford's Law. You should not focus on p-values!
